IPC: F16K5/18
Filed: 1922-02-28
Abstract: 177,501. Lemasson, R. March 19, 1921, [Convention date]. Cylinders, valves coaxial with; rotary cylindrical valves.-The working faces of a rotary slide valve are made fluid-tight by surrounding the ports with circular and straight packing pieces. As applied to an engine cylinder, Figs. 1 and 2, the valve is formed by a cylindrical sleeve 3 rotating between the upper part of the cylinder 1 and the cylinder head 2. The valve is provided with ports 4 and the cylinder and head with ports a<1>, e<1>, a<2>, e<2>. In a four-stroke engine the sleeve 3 rotates at one quarter of the speed of the engine shaft. To prevent leakage, the ports in the cylinder wall are surrounded by packing elements 5, shaped as in Fig. 3, and 9 which are similarly shaped but without the branch 8. These elements are not elastic but are combined with expanding rings such at 15, Fig. 6, placed in circular grooves behind the packing elements. In a modification, the grooves may not be circular, but only the length of the packing around the ports, in which case the expanding members are pressed outwards by plate or spiral springs. The expanding rings may be ordinary piston rings, or may be constructed with elastic tongues 16, as in Fig. 6. The above arrangements are applicable also to valves which are inside the cylinder or outside it but not concentric, when the packing elements and rings are carried by the valve instead of the cylinder. In a modification, Fig. 10, the packing elements comprise two notched circular rings 8<a>, 8<b>, each consisting of two or more arcs of a circle placed end to end. The upright portions 18 are independent of the circular portions and extend into the notches. Expanding rings are arranged below the packing-members and press against the circular portions and the ends of the upright portions. Valves packed in this manner may be used in internal combustion, steam, or compressed air engines, pumps, or compressors, or for other purposes.

Title: A prehensile hook and engaging ring for lifting loads
IPC: B66C1/54
Filed: 1967-02-08
Abstract: 1,111,176. Article engaging and lifting devices. A. A. S. HAINES. 8 Feb., 1967 [27 July, 1966], No. 6010/67. Heading B8H. A load-engaging and lifting device comprising a body supporting three pivoted hooks 14 which engage a ring member 21, 22, 23 attached to the load, has three electromagnets 7 which hold the hooks in their disengaged position. When the load is set down further lowering of the lifting device causes a plate 24 to abut the plate 20 of the ring member. The parts 1, 2, 3, 4 and 5 continue to descend until a plate 5 supporting the magnets 7 abuts a plate 15 which is attached to the plate 24 by fins 13. As this relative movement takes place the hooks 14, which are pivoted to the fins 13 at 12, are swung inwardly by pins 9 mounted on the members 4 which depress lugs 10 of the hooks. Energization of the magnets 7 holds the plate 15 against the plate 5 and so holds the hooks in the retracted position. When a load is being lifted the lugs 10 are raised by bars 11. In the load engaging position the plate 15 is too far away from the magnets 7 to be attracted thereby. An annular guide 19 prevents the device from tilting as it is lowered on to a load. Instead of being recessed into the load the ring may be raised, Fig. 2 (not shown).
